Fig. 5 is also a similar view extreme tilt of the cradle.

to discharge the material from illustrating the Fig. 6 is an enlarged fragmentary end view showing the cradle, car, and clamp.

Referring now in detail apparatus consists briefly of a can be of any to the drawings, the:

frame 5 which desired design. The cars are krun to discharging position over a trestle 5 between the ends of which that the car can dumping. The car be run onto a car cradle 1 is located so the cradle for dumping cradle carries track rails 8, and when the car 9 is run onto the cradle, it is shifted to position wall of the cradle by means 5 shifting mechanism (not shown against the side of conventional l, so that when the cradle is tilted, `the car will not shift thereon.

The cradle is raised and lowered in the conventional manner, and clamps I0 serve to rigidly secure the car in position, these clamps being pivotally connected to clamp brackets Il by 5 means of the pins I2. Brackets I3 are secured to one or more of the clamps I0 in spaced apart relation, and beams I4 are secured to these clamps, said .beams being spaced by means of a rod 15 on which a pipe separator I6 is mounted. 10 A preferably flat plate member I1 is secured to the beam members I4 in any approved manner, and is provided with a lip section I8 which is .connected to the main plate by means of hinges I9, and when the car is swung to dis- 15 charging position as shown in Fig. 4 of the drawings, this lip swings outwardly, by gravity,

for metering and controlling the discharge of the material.

Laterally disposed pivot pins 20 are provided 20 on the ends of the cradle, and brackets 2i are girder frame 22, and which the pinsA 20 engage when been raised to dumping position.

Legs 24 are provided on the cradle in spaced relation, and links 25 are pivotally connected thereto by means of pins 25, the outer free ends! of the links being bent as shown, and sheaves* 21 are secured thereto. 30

The cradle raising mechanism comprises a cable 2B which is anchored to the frame at the point 29, and a sheave 30 is secured to the cradle, said cable being trained around the sheave 30, thence leading up and over the sheaves 3l and 35 32, thence down and around the sheave 21, thence up and over the sheaves 33 and 34, and thence down to a cradle hoisting drum (not shown). Cables 35 are connected to the clamps I0 and lead around the sheaves 36, and thence 40 over the sheaves 31, thence being connected to the counterweights 38 so that the raising and lowering is facilitated.

When the cradle is raised to position so that the pivot pins 20 engage the sockets in the 45 brackets 2l', the cradle will be fulcrumed and swung up and around so that the material is dumped against the plate I1, said plate being so positioned as to leave a relatively narrow discharge opening through which the material can be discharged. The material flows outwardly in a steady stream, the lip section I8 swinging outwardly, metering the material and holding large lumps in the stream, thus eliminating breakage and the consequent lines and slack. The

plate and lip are of a length to cover the car. and the plate is disposed at a predetermined distance from the top so that as the car is tipped, there will be very little dust and the movement of the coal or material will be free and easy. A stationary plate 39 prevents the material falling and closes the gap between the frame and the end of the apron 4|, thereby eliminating shocks and sharp drops as the material is unloaded, a housing |32 being provided on the movable girder 42 as usual.

From the foregoing description it will be obvious that I have perfected a very simple, practical, and economical means for regulating and controlling the flow of material as the car is being dumped.

What I claim is:

1. The combination with a material handling apparatus of the character described and including an inclined discharge apron and a cradle adapted to accommodate a car, clamps pivotally connected to the apparatus, a flat cover member'secured to said clamps, and forming a closure for the upper end of the car when it is tilted to discharge its contents, and a hinged section on the one edge of the cover, said section being adapted to swing up and form a discharge opening between the edge of the car and` the main body of said cover when the car is being tilted.

2. 'Ihe combination with a material handling apparatus of the character described and including an inclined discharge apron and a cradle adapted to accommodate a car, clamps pivotally section hingedly secured thereto, said cover and lip section forming a closure for the upper end of the car, said lip section swinging outwardly as the car is being tilted to form a discharge opening between the edge of the car and the main cover section to control and meter the material discharging from the car into the apron.

3. The combination with a material handling apparatus, including a cradle adapted to accommodate a car, clamps pivotally connected to the apparatus adjacent the one edge of the car, a flat cover plate secured to the clamps, a free swinging lip section hingedly secured to and forming a continuation of said plate, said lip being disposed directly adjacent the clamp pivots and adapted when the car is tilted to swing outwardly and form a discharge opening between the edge of the car and the cover plate.
